Il Magnus 2,4-16 × 56 offers the human pupil an enormous space. Added to this convenience for the eye are the optical construction with the oversized ocular lens assembly and lens coating technology. All this gives to those who aim with the Magnus a sensation never before experienced of brightness and absence of constriction for the eye. We explain why. Light transmission is the part of light existing in the environment, which once entered through the lens can travel 8-10 and slower than a rifle scope and reach up to the eye that is aiming.
If it is true, in fact, that the more light reaches the eye at dusk, the better, in order to give the right weight to commercial messages it is good to know that no human eye is able to perceive the difference in light transmission offered by a telescope. 92% compared to one from 95%. Accuracy limits of our eye, or of the brain, if you like. Science says that it takes at least a 5% difference for man to be able to perceive it. It is essential to know that the ability of the telescope to allow aiming up to the limit of the night is not only due to the transmission of light. The light, that is, the image, in fact, must be "tamed", designing the architecture of the optics and working the lenses (and their anti-reflective coatings!) in such a way as to tend as much as possible to eliminate chromatic aberration (the halo that appears around the silhouette of the animal that is observed) and ensure perfect contrasts (the definition of the edges of the animal with respect to the background).
With the same light transmission of two optics, the one with the best contrasts will allow the eye to see the silhouette of the animal with the contours more clearly defined than the background and when evening comes it is precisely not being able to distinguish the animal anymore. compared to the background the one that literally sends the hunter home. If you compare various optics with similar light transmission in the field (between 90 and 96%), you can see that in extremely low light conditions, it is not the one with the greatest transmission that wins, but the one that offers the contrasts and the pupil. better output, thanks to these features the great advantage of not immediately tiring the eye and also that of allowing you to hunt for a few more precious minutes.
The exit pupil is the space inside the optic in which the human pupil has the freedom to move to aim and can be evaluated in its dimensions by looking at the optic from about 40cm away (from the eyepiece side); Contrary to the case of binoculars, for which the diameter of the exit pupil is a purely arithmetic function (diameter of the objective "divided" magnification), in the rifle scope it depends on the ability of the engineers to conceive an optical architecture that offers an generous exit pupil. The larger the exit pupil, the less tiring and dangerous it will be to aim for a pupil that dilates at dusk or in low light conditions. The Leica Magnus offers an exit pupil diameter of 12.1 mm (at minimum magnification). These are record-breaking measures. It is a huge space.
To complete the high quality of the optical part of the Leica Magnus 2,4-16 × 56 spotting scope it is the very sturdy mechanical part. The Leica Magnus 2.4-16x56i from Leica boasts a particular internal construction with the reticle resting on a tube embedded in the main one designed to give maximum strength of its components. The click mechanism is made of 60 HRC steel to ensure precise and safe reticle movement and sealing even with heavy calibers.
In conclusion, thanks to the optical perfection of the lenses, the record exit pupil and the infallible mechanics, the Leica Magnus 2,4-16 × 56 it is the best rifle scope for selective hunting on the market today.
